Although annoying that Nissan would even bother making a non-lighted variant, I find the problem is easily overcome. I place the tip of my left ring-finger on the lighted window switch (A). From that landmark, my left middle finger falls to the switches above and tactile identification is straightforward; one bump on the left, 2 on the right.

Although it is frustrating that the buttons do not light, knowing the lock buttons is not an issue.

IN THE DARK.... Start at the top of the button cluster.. The top right button is to lock. Slide finger down from there, and the unlock button will have a 90degree cliff going downwards... That is the unlock... end of problem/
